I want to upgrade jQuery inside my drupal installation. At the moment I have jQuery 1.2.6 and I would like to upgrade it to jQuery 1.4
I guess some Drupal modules still depends on the old jQuery version. I've tried jquery_update module to upgrade jQuery, but it didn't work. It asked to replace the original Drupal files in the "misc" folder with the new ones, but it didn't work.
Anyway, I was wondering if there is a better method instead of using another module
thanks
the jquery update module doesn't install jquery 1.4. you need to manually update the jquery.js.
jQuery 1.4 breaks quite a few ajax bits in the admin UI, which are pretty essential. Luckily you can get around this by loading a different version of jQuery depending on what page you are currently viewing.
I recommend using the jQuery update module and modifying it with one of the solutions here (#7 or #11):
A very nice solution is the following, especially for people who do not feel very comfortable patching any part of drupal.
The author provides a clean way of running the default jquery version and any other version (of your choice) - side by side.
Take a look at the jQuery update module
I ended up creating my own solution based on a couple discussions on Drupal.org
It's available on GitHub and works 100% with Drupal/Pressflow 6 and jQuery 1.5.2
